Doing a separate module has been the first thing I tried. But there are
several reasons which made me try differently  :
* I needed finer control by being into module-bluetooth-device than hooks :
when a sink is being removed it is not possible to remove the sink inputs
that were previously affected to it because the sink input has started
moving and this triggers an assertion. I had to unload module-loopback
before the sink inputs would start moving.
* I wanted to avoid having loopback enabled for unwanted modules that could
cause uncontrolled side effects.
* IIRC Some specific other modules (USB) could benefit of similar behavior.
* The code isn't too big.

Maybe I'm trying to get complicated in that I'd rather explicitly remove
the loopback instead of letting it die.

So that's not a big bunch of work to do a module, but I'm open ideas to fix
the issues encountered before that. It's an RFC after all ;)

Regards,
Frédéric
